Abstract Research on three-phase inverter modulation wave based on the space rectangular coordinate system is presented in this paper, and the concept and characteristics of 3-D space modulation wave vector and new research methods is presented as well. Analytical expressions of SPWM and SVPWM can be obtained with modulation wave vector, which makes the modulation method, control strategy and the main circuit model can be analyzed and modeled in the unified form. The Judge condition for over modulation is presented as well. This new method is correct, clear, intuitive, easy to calculate, which is proved by simulation and experiment.

Key words： 3-D space rectangular coordinate system modulation wave vector over modulation
